Definitions

  • the present invention relates to an electric refrigerator, and more particularly to a technique for eliminating temperature unevenness within a refrigerating compartment to improve a food preservation state.
  • an electric refrigerator has several storing compartments such as a refrigerating compartment, a vegetable compartment and a freezer compartment, which are set at different temperature zones.
  • a refrigerating compartment 100 having the highest frequency of use from a human engineering point of view is placed at its uppermost stage, and at its lower stages, a switchable compartment 200 such as a chilled compartment, a vegetable compartment 300 and a freezer compartment 400 are placed.
  • the temperature in the switchable compartment 200 is made selectively adjustable between a freezing temperature zone and a refrigerated temperature zone in accordance with a contained object such as a chilled food.
  • a chill is generated by a heat exchanger (evaporator) 1 connected to a compressor C, and the chill is supplied to each storing compartment 100 to 400 through a duct 3 by a blower 2.
  • a housing for the main body R of the electric refrigerator consists of an inner case 4 and an outer case 5 which have been assembled with thermal insulting material interposed therebetween, and on the back surface side within its compartment, between the back surface and the inner case 4, there is provided a duct cover 9 forming the duct 3, and the heat exchanger 1 and the blower 2 are disposed within the duct 3.
  • the chill is supplied to the refrigerating compartment 100 and the switchable compartment (for example, chilled compartment) 200 and the like from their back surfaces, and is returned to a suction side of the heat exchanger 1 through a predetermined chill return duct.
  • the chill supplied to the refrigerating compartment 100 is conducted into the vegetable compartment 300 through a by-pass pipe 6, and thereafter, is to be returned to the suction side of the heat exchanger 1.
  • the vegetable compartment 300 is placed under the refrigerating compartment 100, however, on a partition wall between the refrigerating compartment 100 and the vegetable compartment 300, the is provided a ventilation port in such a manner that the chill is supplied from the refrigerating compartment 100 to the vegetable compartment 300.
  • a conventional electric refrigerator Since it has adopted a back surface blow-off system in which the chill is supplied from the back surface side of the storing compartment, a conventional electric refrigerator has had the following problem. That is, as regards the storing compartment 100, since its shelf plates are filled with foods in the majority of cases, they become an obstacle to supply of chill, thus making it difficult to cool the front surface side of the refrigerating compartment 100.
  • the refrigerating compartment 100 is kept in a substantially hermetically-sealed state by a door D, but heat always enters through its gasket portion. Since the door D of the refrigerating compartment 100 has a high open-and-close frequency, particularly on the front surface side of the refrigerating compartment 100, comings and goings of heat are heavy. From these reasons, between the back surface side and the front surface side of the refrigerating compartment 100, there has been caused temperature unevenness.
  • the refrigerating compartment 100 requires the largest amount of chill, but the heat exchanger 1 is arranged below the duct 3 because of relationship with the compressor C and a duct course until the chill reaches the refrigerating compartment 100 is long. Therefore, the chill becomes higher in temperature due to heat exchange with the outside in a process, in which the chill moves, and chill loss caused by this movement is also great.
  • the above-described conventional chill circulation system has had the following problems.
  • a temperature within each storing compartment can be individually controlled independently of other storing compartment temperature.
  • the vegetable compartment is partitioned into a low-temperature vegetable compartment and a high-temperature vegetable compartment, it is possible to adjust temperature within each compartment individually and appropriately.
